				Complex!(CommonType!(T,U)) fromPolar(T, U)
				(
				

				  const T modulus,
				

				  const U argument

import core.math;
import std.math.operations : isClose;
import std.math.algebraic : sqrt;
import std.math.constants : PI_4;
auto z = fromPolar(sqrt(2.0L), PI_4);
assert(isClose(z.re, 1.0L));
assert(isClose(z.im, 1.0L));
